Copyright Goodheart-Willcox Co., Inc. Chapter 6 PLC Programming 111 The Title page option prints the RSLogix 500 name and the Rockwell software logo. Printing this page requires a lot of ink from an inkjet printer. Therefore, do not select this option. The Processor Information option contains the name and type of processor used in the PLC system. Processor type 1747-L20A is one of those used in the fixed SLC 500 PLCs. Processor type 1747-L532 is one of those used in the modular SLC 5/03 PLC. You should already know the type of PLC you are using with your lab station. Therefore, you do not need to select this option either. The I/O Configuration report displays the number of slots available on the PLC. It also displays which slots are configured to be used and how many ports each module in the expansion slot has. Finally, it prints the number of input/output devices used. The fixed SLC 500 PLC has one slot or module. It is addressed as slot or module zero. Slot zero is used with the 1747-L20A processor and has twelve input and eight output ports. These ports are rated for 120 VAC input/output operations. The modular SLC 5/03 trainer has four slots or modules. Slot zero must always be configured for the processor type 1747-L532. Slot one is configured for a module that has sixteen input ports (1746-IA16). Slot two is configured for a module that has sixteen output ports (1746-OA16). All the input and output ports are rated for 120 VAC operation. The Channel Configuration report lists the controller channel number used for communication between the PLC and the computer. The PLC is assigned to station or node zero. You should configure the AB_PIC-1 (Allen-Bradley Peripheral Interface Connector) device driver that uses channel one. Channel one is the channel used to connect the PLC to the PC or to other PLCs. It has an RJ-45 connection terminal. The RJ-45 terminal looks similar to the RJ-11 telephone jack terminal, except the RJ-45 is larger than the RJ-11 terminal. Channel one is always used to connect the 1747-PIC communication interface device to the PLC and the computer. Channel zero is used to connect peripheral devices such as a barcode reader or a printer directly to the SLC 5/02, SLC 5/03, SLC 5/04, and SLC 5/05 PLC systems. Channel zero uses the RS 232C (Recommended Standard 232C) channel available on these PLC systems. Since channel zero is usually used for connecting a barcode scanner or a printer to the PLC, most commonly used PLC trainers do not use channel zero. These trainers use channel one. Therefore, you do not need to select this option. The Custom Data Monitor report provides you with a list of the addresses in the custom data monitor, their symbols, and the current value of the bit or word address. For the smaller SLC 500 and SLC 5/01 programmable logic controller systems, you do not need to print this report. The Cross Reference report specifies which data files and rungs the addresses in your project are using. For smaller ladder logic diagrams with only a few rungs, you do not need to print this report option. Special The Special section contains special configuration options. It also includes a Multipoint List option and options for printing the program’s revision history. A Multipoint List report contains a list of addresses used in the ladder logic diagram. These addresses can be for input/output devices (I/O), contact bits (B3 or B10), timer (T4), counter (C5), control register (R6), or status register (S2). This is available only with Allen-Bradley MicroLogix 1000, SLC 5/03-OS302, and SLC 5/04-OS401 controllers. The multipoint list reports the addresses used and their conditions or states while the PLC was operating. Occasionally, you should select this option to review conditions while troubleshooting your PLC project.
